Case Study: Calibrating Pressure Gauges in High-Pressure Applications

Case Study Calibrating Pressure Gauges

In another customer case study, former Haskel employee and current Product Specialist at FLW, Ray Schnell shares his expertise in product design modification. Backed by 40 years of experience in the high-pressure equipment market, Ray troubleshoots and finds solutions for complex customer challenges. Read the case study below to learn how he helped one team improve production room conditions and productivity. 


The customer was having difficulty with their high-pressure pumps. The pumps required airline oilers, but the poorly-designed equipment in place was causing the air drive exhaust to fog up the production room. This led to unhealthy working conditions within the plant.

The issue was brought to FLW by a new plant engineer who wanted to improve working conditions and productivity. After talking through performance requirements and facility specifications, our FLW team came up with a solution.


Our team assembled a Haskel air-driven pump with a few modifications. One of the biggest factors in recommending this product to the customer is the high-quality seals that are in every Haskel pump. Their air-driven pumps are pre-lubricated and do not require any airline lubricator either. All of these factors would significantly improve the functionality of the air-drive exhaust in the customer’s plant.

To further improve the product functionality for customer operations, our team also addressed the gauge calibration issue using a CPO precision air regulator with a recycle modification that allowed the customer to start at lower pressures. The regulator eliminated pressure spikes because of its ability to be inched in for better pressure control. Using a Haskel pump as the core product also allowed them to use a recycle button.

With the capabilities of these new pump modifications, the customer could now design their own equipment benches for better control and stability, aligning the design of the bench to that of the product.

We had originally loaned the modified pump to the customer, telling them to test it out for a month to make sure it fit their needs. They called when the month was up, requesting three identical pumps. They are now up to 30 Haskel pumps. The pumps are easier to maintain, allowing the customer to better utilize their in-house service team.
